“…VR environments have enabled researchers to conduct experiments in a simulated real-world, which may elicit responses from the patients similar to those in real situations (Gourlay et al, 2000;Lee et al, 2003;Klinger et al, 2013). There is a lack of studies on holistic assessment of functional vision in individuals with low vision in a VR environment.…”

Introduction: Virtual Reality technology helps in creating virtual environments for evaluation of visual performance of low vision individuals with holistic experience. The purpose of this study was to develop a virtual reality (VR) platform for the objective assessment of functional vision in patients with low vision in two categories, central and peripheral vision loss . Materials and methods: Focus group discussions (FGD) were organized to understand the difficulties faced on a day to day basis by patients with low vision. Based on the results of the focus group discussions, a virtual bank scenario incorporating specific visual tasks was developed. A pilot study was conducted which involved people with normal vision; low vision Patients secondary to central field loss (CFL) and peripheral field loss (PFL). Each subject completed all the tasks in the objective assessment; the data obtained from the assessment were further analyzed to understand the pattern. Results: Comparing the three groups, there was a significant difference in distance (central field loss was lowest) and near visual angle, and three visual search tasks (peripheral field loss was lowest). In assessing the time taken, peripheral field loss group was again found to take the most time to complete tasks. Conclusion: Based on a newly developed virtual reality platform, assessment of functional vision of specially abled persons could be tested and was inferior to that of normal sighted persons. in a close to realistic environment. Multiple visual tasks were performed in the virtual environment and the visual performance was compared among all three groups of participants. Participants were matched for age and gender. Irrespective of the nature of tasks, visual performance of the normal group seemed significantly better than people with CFL and PFL.

“…Within the professional education programmes in health care, simulation is used as a method to increase empathy and generalized awareness of disability characteristics (Gordon et al, 2005; Wilson et al, 2009; Zagar &Baggarl, 2010). For instance, low vision and visual field problems can be simulated with the use of simulation goggles or simulation software (Klinger, Boumenir, Kadri, & Mury, 2013; Thompson, Legge, Kersten, Shakeseare, & Lei, 2017). Al-Fadhili designed a 3D simulation for the visual field problems which people with CVI experience during navigation (Al-Fadhili, Chung, Li, & Bowman, 2018).…”

We designed a cerebral visual impairment (CVI)–experience toolbox containing simulation exercises to let professionals experience the complexity of visual information processing and to get an impression of what it means to have CVI. We measured the benefits of the CVI Experience toolbox by using questionnaires during three CVI seminars with professionals ( n = 69). These seminars started with a slide presentation on CVI followed by the CVI experience toolbox. We presented the professionals with the same survey on their knowledge of CVI at the start of the seminar, after the presentation, and after the toolbox. Professionals with more previous CVI experience started on average with a higher score. The final end score, however, did not seem to depend on previous experience. Furthermore, the added value of the experience toolset was quite independent of the added value of the presentation. The results indicate that both the presentationand the experience toolboxadd to the understanding of CVI.
